What's a Wii?
Lisa, responding to your comment, you don't know how lucky you are that your 7-year-old doesn't know what a Wii is yet. It's the latest Nintendo gaming system -- an update of the GameCube. Some aspects are pretty cool -- you swing the controller around to bat or move as opposed to just pressing buttons. With any luck, he won't discover it until after the holiday is over and the price goes down!
